I purchased the I450 two weeks ago. I do not know how long the battery life is yet, but the pictures are very good. The nighttime flash does work up to 50+ feet. This camera also has a $20.00 rebate going until the end of the year. If the retailer you purchase from does not provide you with a rebate form, you can download it at the Stealth website. Stealth has a very nice website as well...check it out!
